TUBE-THOUGH FOR TUBE-MILLS.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed May 5, 1906. Serial No. 315,320.

To all whom it may concern:

Be it known that I, JOHN S. WORTH, a

citizen of the United States, residing at Ooatesville, Pennsylvania, have invented certain Improvements in Tube- Troughs for Tube-Mills, of which the following is a specification. My invention relates to certain improve ments in troughs for conveying tubes, during the process of manufacture, from one machine to another of a tube mill.

One object of my invention is to provide means for driving the tube through the trough.

A further object of the invention is to provide an adjustable guard extending over the trough so as to retain the tubes in the trough should they twist or buckle either in passing from one roll or passing into the other.

In the accompanying drawings :Figure 1, is a side view of my improved tube trough; Fig. 2 and Fig. 2 are enlarged side views similar to Fig. 1, but more clearly illustrating my invention; Fig. 3, is a plan View of Fig. 2 Fig. 4, is a transverse sectional view on the line 44, Fig. 2; Fig. 5, is a transverse sectional view on the line 5 5, Fig. 2 Fig. (3, is a longitudinal sectional view on the line 66, Fig. 7; Fig. 7, is a sectional plan view on the line 77, Fig. 6; and Fig. 8, is a sectional view of the trough showing the guard lowered in position to guide a tube.

My present invention is particularly designed to convey a partly finished tube from the sizing rolls of a tube mill to the straightening rolls, and I have found that it is desirable to provide means for propelling the tube while in the trough, so that it will properly enter the straightening rolls, and the guard which rests above the trough, retains the tube in the trough. This guard is vertically adjustable so as to accommodate different sized tubes, at the same time it can be quickly raised in the case of an accident so that an imperfect tube, for instance, can be quickly removed from the trough before it enters the straightening rolls; and while my improved trough is especially designed for the purpose indicated above it will be understood that it can be used at any point in the mill where it is desirable to convey a tube, or can be used in mills manufacturing rods or other shapes without departing from my invention.

A is the trough, made of a series of sections bolted together at a and of any length desired.

A is an end section which is shaped to fit closely to the roll structure through which the tube must pass into the trough.

The trough is V-shaped, as shown in Figs. t and 5, and projecting vertically from each edge of the trough is a series of earns a having inclined surfaces a on which are supported the bearings for the adjustable guard which is situated directly over the trough.

There is a series of openings (0 in the bottom of the trough as clearly shown in Fig. 6, and mounted in the hangers B is a spindle 0 of a roller C, this roller extends through the opening a in the bottom of the trough and it can be adjusted so that the roller will bear upon the tube and propel it through the trough. There is a series of these rollers placed a given distance apart and they are raised just sufiiciently above the trough to prevent bending of the tube and to reduce the friction on the trough itself. The rollers are each vertically adjustable so as to take up for any wear and in the present instance they are hung-from a portion a of the fixed bearing formed integral with a section of the trough in the present instance, and this bearing is perforated for the passage of a shaft C. Bushings c are provided in which the shaft is mounted. On one end of the shaft is a gear wheel 0 which meshes with a gear wheel (2 on the shaft 0 carrying the wheel C, and on the other end of the shaft is a bevel wheel 0 which meshes with a bevel wheel (Z keyed to a longitudinal shaft D extending along one side of the trough. Any means may be provided for driving this shaft D, although I have shown in Fig. 4 special means which will be described hereafter.

The hanger B has an extension 5 through which passes a screw threaded bolt Z) which is hung at b to the trough and has nuts 5 on turning which the hanger may be raised or lowered. hanger is made in twoparts, the portion 5 forms the lower part ofthe boxes Z2 for the shaft 0 while the arms 5 swing on the proj ecting portions a of the fixed bearing.

The longitudinal shaft D is mounted in In the present instance the and. this shaft is mounted in a step bearing 6 at the lower end and in a bearing 6 car ried by a bracket E secured to any fived portion of the mechanism. The shaft E has at its upper end a bevel wheel 6: which meshes with a bevel wheel c on the hori- Zontalshaft E driven by the driving. mechanisniof. the sizing rollsor the straightening rolls, as desired. It will be understood, however, that this mechanism may be changed without departing. from my invention, as an independent means may be used for. driving the shaft D if desired.

F is. a, frame mounted on standards f, f projecting from the sides of the trough A; and mounted on this frame in the present instance is a cylinder G. lnfront of the cyl-' inder are guides G for the slide H and carried by the slide is a piston rod it having a piston in. mounted inthe cylinder G.

I isacarriage arranged to travel on the bar It andsecured to the carriage is a rod 2' having a screw threaded portion. 71 which passes. through a nut 2' mountedin the slide H, sothat in turningthis nut the distance between the slideHv andthe carriage 15 may be increased or decreased as. desired. The carriage .I in the present instance has .fianged wheels 2' which rest on the frame F, and also has. proj ecting. portions 713.

The guardin the present instance is made upvofa frame J consisting. of two longitudinal angle bars K extending the full length ofit-he trough and preferably turned up. at eachend, and angle bars made in two setsK, K as clearly shown in Figs. 2 and 2 The angle bars K, K are secured at intervals. to axles 7e and are arranged as shown inFig. 5, being secured to the axles by boltslc;

The angle bars K, K are secured to blocks by bolts/v and eachblock has. astem 7% which extendsthrough an axle 7s, and issecured thereto. by. a nut 76.

It Will'be noticed that the guard proper formed by thebars K, K isinthe form of an. inverted. V, so that when the guard: is lowered as in Fig. 8, it forms, with. the trough, away for the tube so that the tube cannot be deflected. out of its course. On the. trunnions. of the axles. 7c are flanged wheels jwhichtravel on the inclinedwvays a ofthe projections a of the trough. The position of these rollerson the inclinedsways isregnlated by. the nut. 2' of the slide H, by. turningthenut the carriage I is moved toward i013. from thesaid slide. and-the posi tion OfitllQWllGBlS j ,on the inclined trough a? defines or fixes the position of the guard J in respect to the trough. The parts are so arranged, however that when it is desired to. quickly elevate the guard in the case of an accident, 01' it is desired to remove a tube, the hydraulic or steam valve g in the supply pipe 9 can be turned so as to force the plunger forward and this forward movement will cause the rollers to travel up the incline and thus raise the guard sutficiently so that access can be had to the trough. In Figs. 2 and 2 the parts are. shown-with. the guardv raised to itsv full height. The details of construction of the guard may be modified without departing from my invention. In. the present instance the trough is. mounted on a standard M consisting of a base m. and a screw threaded portion m, and mounted on the-screw threadedportion is a nut m so that on turning. the nut the trough can be vertically adjusted. Any other. support may be used without departing from my invention.

The operation of the mechanism is as. follows: If a given size of tube is to be made the nut, 2' is adjusted sov as to bring the guard to such a positionin the trough that the tube will pass freely through the trough without touching the guard, the hangers B are so adjusted as to lift the rollers that. they will support the tube in' the trough, thenv the mechanism set: in motion, all the rollers being preferably driven from. the same source of. power, namely the longitudinal shaft D, and the tubes come from the rolls they pass into the trough and are fed forward at a given speedby the rollers to the straightening rolls or other, machine.

If it is desired to remove any one of the tubes while in the trough, the guard J can be quickly elevated by simply turning the valve 5 of the supply pipe to the cylinder G so as to admit fluid to the cylinder when the slide and carriage will be moved forward and the rollers supporting the guard will travel up the several inclined planes. Thus raising the guard to such a heightthat; access may be had to the trough and the tube can be removed from either end of the trough.

It will be understood that any power may be. used to, operate the guard, either fluid under pressure, electricity or other prime mover.
